Emma Willis hosts the seventh series of the singing contest, which this year sees Olly Murs joining returning coaches Will.i.am, Tom Jones and Jennifer Hudson on the famous spinning chairs. The search for a star kicks off, as usual, with the first in a series of rounds of blind auditions, as the panel listen to each contestant with their backs turned, ensuring that they judge the performance on the strength of vocal ability alone. Those who succeed here will progress to the Battle and Knockout phases.

The Blind Auditions continue in the third instalment of 'The Voice UK'. With spaces on their teams filling up, the competition is getting tougher as coaches will.i.am, Jennifer Hudson, Olly Murs and Sir Tom Jones continue their quest to find the nation's best vocal talent.
